CALCULATlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 709,362, datedSeptember 16, 1902. Application filed December 18, 1901. Serial No.86,455. (No model.)

To @ZZ whom t may concern:

Be it known that I, ALEXANDER C. SCHU- MAN, a citizen of the UnitedStates, residing at Louisville, in the county of Jefferson and State ofKentucky, have invented a certain new and useful Improvement inCalculating- Machines, of which the following is a full, clear, andexact description.

This invention relates to that class of machines by means of which theprocesses of addition, subtraction, multiplication, and division may beperformed mechanically and accurately and the result duly recorded,- andit is an improvement upon the machine shown in myapplication filedDecember 19, 1901, Serial No. 86,514.

The invention comprises setting mechanism, registering mechanism, andrecording or printing mechanism, all so combined and arranged that whencertain keys corresponding to the number of the sum to be done areactuated by the operator the several mechanisms are therebyautomatically so arranged that they can be properly set in motion by amanuallybperated device, such as a crank, and the registering andprinting properly effected.

The several mechanisms of the machine are contained Within a suitablecasing, which may beofanydesiredkindandfinish. Inthedrawings I havemerely illustrated supports for the various mechanisms. The settingmechanism comprises finger-operated keys which when depressed willarrange stops to limit the movements of vibrating levers which arereleased by the depression of the keys. The machine is provided with arow of nine keys, one for units, another for tens, and so on for eachdenomination, as is customary, and for each row of keys there are acorresponding registering Wheel or disk and a vibrating lever andconnections, the lever being limited in its movement by the position ofthe key depressed and being positively returned to normal position bymanually-operated devices, hereinafter described, and during its returnthe registering-disk is actuated and caused to effect the properregistration of the number indicated on the depressed key. The vibratinglever, moreover, is connected with and controls the setting of atype-carrierin the printing mechanism, so that each time the lever isreleased the proper type will be presented at the printing-point, andarecord may be taken therefrom, if desired. The con-1 struction,connections, and modes of operation of the several parts will behereinafter more particularly described, with reference to theaccompanying drawings, forming part of this application, and whichillustrate the best form of the invention now known to me.

Having thus briefly stated the nature of my invention, I will proceed todescribe the same, referring to the claims for concise summaries of thenovel features and combinations of parts which I claim as my presentinvention and desire to secure by Letters Patent thereon.

In the accompanying drawings,illustrating my invention, Figure 1 is aside elevation of that side of the machine upon which theoperating-crank is arranged, with the outside casing removed and theparts being shown in the position of rest. Fig. 2 is a side eleva tionof the opposite side of the machine, the casing also being removed andshowing the parts in position ready to effect the registration andrecording.

The keg/board cmd connections for setting the parte preparatory toefect'zng ct regstraton.-At the front and top of the machine are anumber of rows of keys 7', having stems 7, which depend through suitableguides. Beside each row of key-stems is a sliding bar 1, having nineobliquely-disposed notches 2, having offsets 3 at their lower ends. Eachbar 1 has an extension 4, which is connected by a pin-and-slot jointwith the upper end of a bent lever 5, mounted loosely upon a transverseshaft 6. Each key-stem 7 has a laterally-projecting pin 8, engaging theadjacent notch 2 in the relative sliding bar and effecting thelongitudinal movement of that particular bar when the key is depressed,and this movement of the bar rocks the connected lever 5 and causes thelatter to release the corresponding main vibrating setting-lever 10, tobe described. The keys 7l are normally uplifted by springs, which areshown in Fig. 2 as coiled springs 9, having one free end acting againstthe bottom of the casing 1a, in which bars 1 are contained, and anotherend against the pins 8. As shown in Fig. 1, springs 9a act against pins9b on the stems to lift them. I do not consider the arrangement ofsprings material. The bars 1 are returned to normal position by springs9c, as indicated in Fig. 2. When a stem 7 is depressed, its pin 8cooperates with slot 2 in bar 1, causing said bar to travel forwardlyagainst the tension of spring 9C, and when the key-stem is fullydepressed spring 9c pulls bar 1 rearwardly until offset 3 is engaged bypin 8, thus locking the key-stem in depressed position, and as therearward movement of bar 1 is less than the forward travel (owing to theoffset 3 being short) the bar 1 will be held in such position that thepins 8 of the other keystems in this row cannot enter slots 2, andconsequently said keys are locked in their raised position until thedepressed ke r is released. This release is effected by pushing har 1forward until offset 3 disengages pin S, when the key-stem will belifted by its spring and spring 9C of bar will restore the latter to itsnormal position. The bar 1 is automatically pushed forward after theregistering and recording operations have been effected by the returnmovement of the main vibrating setting-lever l10, as hereinafterexplained, there being one such lever 10 for every row of setting-keys,and as all levers 10 are substantially alike the description of one willsuffice for all. The several vibrating levers 10 are arranged upon atransverse shaft 11 and are normally impelled toward the front of themachine by means of springs 12, coiled on said shaft and engaging a xedpart 12FL of the frame at one end and a projection on the lever 10 atthe other end, as shown in Fig. 2. The upper portion of each lever 10(see Fig. 7) is provided with a rearwardly-extending arm 10, havinglaterally-projecting lugs 13, arranged in ditferentdistances from thepivot of the lever and respectively adapted to come into contact withthe appropriately-shaped lower end of the key-stems 7 of the related rowof keys when such keys are depressed to control the extent of vibrationof lever 10 and the proper location of the connected actuating-segment22 with relation to the relative registering-disk, as hereinafterexplained, so that said disk may be thereafter moved the num ber ofteeth corresponding to the number on the key depressed. By thisarrangement of lugs keys 7l may be properly arranged and the throw ofthe levers 10 reduced. f

Pivoted loosely to and suspended from a forwardly-projecting arm 21 onthe vibrating lever 10 is a toothed segment 22, having teeth to engagethe teeth of a gear 43 011 the related registering-disk 41. (See Fig.5.) The segments 22 are guided in their vertical movements in slots 23in a plate 24, which is supported upon vibrating arms 26 and 26, thelatter being connected to a. tilting bar 25, arm 26 and bar 25 bothbeing connected to a rock-shaft 27, suitablyjournaled in the frame. Thebar 25 has a cam-slot 28 in its free end engaged by a pin 29 on the endof a swinging lever 30, which is pivoted upon a stud 31, and its lowerend can be swung relatively to the cam-slot 28 by means of a pin 32,projecting laterally from a disk 33, fast on the main actuatingrock-shaft 19. (See Figs. 2 and 30.

latch 34, (see Fig. 16,) pivoted to the lever 30, itswings lever 30forwardly, causing the pin 29 to ride up the cam-slot 2S and depress therear end of the bar 25, and so rock shaft 27 and cause it to move plate24 and the segments 22 away from the registering-wheels, as in Fig. 2.This movement occurs simultaneously with the forward or setting movementofthe main shaft 19, as hereinafter explained. As the main shaft 19turns in ICO l II5 When the pin 32 engages the heel 34"L of a completingthe upward or setting movement of the handle 122 the disk 33 continuesto revolve, and a second pin 32'L thereon comes behind the toe 34h ofthe latch 34. (See Fig. 17.) Thereafter upon the 'return movement ofshaft 19 (indicated in Fig. 17) the pin 32 engages the toe 34b ofthelatch 34 and causes it to swing lever 30 and draw the pin 29 from thehigher to the lower level of the cam-slot 28, and so elevates the rearend of the bar 25, thereby rocking shaft 27 and plate 24 toward theindicator and throwing the segment 22 of the levers 10 into engagementwith the gear of their appropriate registering-disks 41. 1f a key hasbeen depressed, thus setting a lever 10, the segment 22 of such leverwill be thrown into engagement with the gear of its appropriateregistering-disk at the tooth corresponding in number with the number ofthe depressed key, and during the return movement of the main shaft 19the segment is actuated and turns the registering-disk as many teethfrom O to 9 as such lever 10 had been set for. The segments may beAslidably engaged with the plate 24 in any suitable way so as to swingtherewith, as by longitudinal slots 35, embracing a cross-bar 35 of thecarrier.

The slot 2S in bar 25 has an upper and a lower horizontal portionconnected by an inclined portion and serves to lock the plate 24 in bothits forward and rearward positions.

It should be noted that each vibrating lever 10 is locked in its normalposition by the catch-lever 5 until the latter is disengaged therefromby the depression of one of the relative key-stems and the consequentlongitudinal shifting movement of the related. slide 1.

As shown more particularly in Fig. S, each catch-lever 5 is providedwith a hook end 14, on which is pivoted a spring-pressed tumbling-latch15, projecting above the hook 14 and limited in its forward movement bya pin 16, engaging the under side of hook end 14 of lever 5. The mainvibrating` lever 10 is provided with a laterally-projecting pin 17,which when the lever 10 is in its normal inactive position lies behindthe hook end 14 ot' the lever 5, whereby lever l0 is restrained fromactive operation until said hook 14n is lowered by the rocking of lever5, caused by the depression of a key-stem and the forwardly sliding ofbar 1,'by which movement the hook end of lever 5 is depressed below thesaid pin 17, and then the said pin can ride over the tumbling-latch 15until the forward movement of lever 10 is arrested by one of its lugs 13coming into contact with the lower end of the depressed key-stem. As thevibrating lever 10 is returned to its normal position pin 17 contactswith the tumblinglatch 15 on hook end 14 of catch-lever 5, and as thelatch cannot then yield pin 17 forces the latch 15 and end 14 of saidcatch-lever downwardly, and by reason ofthe connection between thevertical arm of lever 5 and the bar 1 the latter is pushed forward untilthe depressed key-stem is released, as before described. J

It will be observed that the pin 17 on lever 10 when the latter is innormal position lies back of the hook end 14 on catch-lever 5, but willengage the latter after making a slight forward movement. This movementis utilized for the carry-over operations,as described in my aforesaidapplication, and occurs whether any related key-stem has been depressedor not; but if no key-stem has been depressed the pin 17 will engageunder the hook 14, and thus will lock the catch-lever 5, so that no keyin its related row can be depressed until thelevers 10 have beenreturned to normal position. This hook 14 is not indispensable, but isuseful to prevent the operator setting any of the keys after he hasstarted to rock the main shaft to put the mechanisms through their cycleof operations until such cycle has been completed and the parts allrestored to normal position.

The setting operation--Wheu a key has been depressed and itscorresponding vibrating lever 10 released, as above described, thelatter is still prevented from moving forward until the main shaft 19 isrocked forwardly, (in the direction indicated bythe arrow on Fig. 19,)because said shaft 19 carries cams 18, (one for each lever 10,) whichengage with pins or rollers 20 on the respective levers 10, and whilesaid cams are intended to positively return the levers 10 to normalposition they prevent the springs 12 throwing the levers 10 forwardlyuntil the cams are withdrawn or eased therefrom.

The wiper-cams 1S are preferably segmental and are fixed on the shaftone slightly in advance of the other, so that they will pick up thelevers 10 successively, beginning with that of lowest denomination, sothat upon the return movement of shaft 19 the levers lO will be broughtback to normal position in one, two, three order, affording time for thecarry-over operations, hereinafter explained. On the forward or settingmovement of shaft 19 the cams 1S draw away from rollers 20, leaving,rthe levers 10 under the control of springs 12, which throw levers 10forwardly until they are arrested by the catches 14 or contact withdepressed keystems, as indicated in Fig. 2.

The peripheries of cams 1S are preferably of sufficient extent to causethe cams to serve as locks to hold the levers 10 in fully-retractedposition so long as shaft 19 is in normal inactive position, and therebyprevent the springs 12, through levers 10, exerting any pressure on thekey bars or levers 5, and also to keep pins 17 out of engagement withhooks 14.

The carry-over devices-ln commercial machines there will be a number ofrows of keys, a corresponding number of Vibrating levers 10, coactingsegments 22, and registering-wheels 41, and in order to carry over froma registering-wheel of lower denomination to the next higherdenomination each segment of the tens and higher denomination has anextra tooth 3G, (see Fig. 5,) which is brought. into action only when acarrying-over is to-be effected.

Referring to Fig. 5, itwill be seen that the segment 22 has a dog 36pivoted to its lower end, said dog having a tooth on its upper IIO IIS

freeend adapted to engage the teeth of the 1 coacting devices forcarrying over from each gear 43 of therelated registering-wheel, aspring 37 normally retaining the dog out of operative position, with itstooth in rear of the teeth of the segment. In Fig. 24 I have shown anexpanding spring 37e as a substitute for the spring 37. (Shown in Fig.5.) A laterally-projecting pin 38 extends from the lower end of the dog36 and is adapted to engage a wiper-cam 40 when the latter is projectedinto the path of the movement of the pin 38, and thereby tilt the dogforward against the tension of its spring and cause its tooth to engageand actuat-e the registeringdisk one extra notch when the segements arereturnedtonormal position. Thewiper-cams 40 are operated as follows: Thecam 40 for the tens-disk is set by and from the unitsdisk. The cam 40for the hundreds-disk is set by and from the tens-disk, and so on. Asshown, an arm 45 is mounted on a rock-sleeve 45a, journaled on atransverse shaft or support 57, parallel with the registering-disks,said arm projecting into the path of a pin 44 on the gear 43 of theunits-disk. To the sleeve 45a, in line with the gear of the tensdisk, isattached the wiper-cam 40, which is adapted to be engaged by the piu 38of the dog 36, carried by segment 22, engaging the tensregistering-wheel. When the pin 44 engages arm 45, it rocks the sleeve45u-and throws the wiper-cam 40 into operative position, and said cam islocked in such position by means ofanger39,which projects besidea hook46, hung from a transverse bar 46L in the frame, said hook being'pressedtoward the bar by a spring 4o'b,which when the finger is raised by thesetting of the wiper-cam catches the nger and holds the latter and camin position until the segments 22 vare raised by the return ofrock-shaft 19 to normal position, during which return movement of theshaft dog 36 engages the gear of the tensdisk andl turns the latter onenotch. Just before the handle 122 on rock-shaft 19-completes its returnstroke there is brought into action an automatic releasing device forthe carry-over cams, comprising a rod 56, which is secured to arock-shaft 57 (which latter also serves as the support for the sleeve45a) and has a rearward projection 58, which is engaged by a lever 59,(see Fig. 1,) pivoted upon a stud 60 on the side of the frame and havingan arm G1, which projects up into the path of movement of alaterally-projecting pin 62 on one end of an arm (i3, fast on the mainrock-shaft 19. The rod 56 extends benealh pins 64, projecting from thehooks 46, and when elevated engages the pins and rocks said hooks ontheir pivots and against the tension of their springs, causing them torelease the fingers 39, permitting the latter to drop by gravity, aidedby springs, if desired, and retract the wiper-cams 40 out of the path ofthe pins 38. It will be understood that there is a similar arm, cam, andfinger and disk of lower denomination to that of next higherdenomination constructed and operating as described.

The several registering-disks 41 are mounted upon a shaft 42 andare freeto turn thereon, and each drum has upon its perimeter two sets ofnumerals from O to 9, arranged in reverse order, as shown in Fig. 13,and each-registering-disk has fixed to it and movable with it a gear 43,having ten teeth, and in addition the laterally-projecting pin 44 forthe purpose of setting the wiper-cam 40 in position to act upon the pin38 to throw its tooth into engagement with the gear, as abovedescribed'. Y

The registering-disks are mounted in a carriage 47, which is adjustablelaterally of the machine and can be held in adjusted position by meansof a spring-latch 48, Fig. 5, engaging one of a series of slots 49 inthe frame. The object of this lateral adjustment of theregistering-disks is to put into and lake out of action the desiredindicator-drums in multiplying and dividing operations, as hereinafterdescribed. Each gear is dogged by means of a spring-actuated device 50,which is held normally in engagement with the gear by its spring, thenmay be collectively disengaged from said gears by means of a rocking bar51, (see Fig. 2,) having an arm 52 projecting therefrom into the path ofa trippinglever 53, (shown in detail in Fig. 10,) having aspring-controlled pawl 54, which may be thrown into position forengagement with a notch 55 in the periphery of disk 33 (beforementioned) on shaft 19. The pawl 54 has a finger 73, which is indirectlyconnected to the total-key,77 as hereinafter explained, so that whensaid total-key is depressed the pawl 54 is actuated by disk 33.

Repeating key connections. In certain calculations, as inmultiplication, for example, it is sometimes desirableto repeat the samesu m indicated by the keys successively a number of times, and toexpedite such operations without necessitating resetting ofthe keys 7 ateach operation 1 provide the setting-key 127,which is connected to arm126, provided with a bail 125,which extends across the machine under thehooked ends of catchlevers 5 and in front of depending tails 15n on dogs15, (see Figs. 1 and 2,) and when key 127 is depressed and held downbail 125 is swung rearwardly and tilts the dogs 15, so that they arekept out of operative contact with pins 17 on levers 10. Consequentlythe levers 1Q can be vibrated repeatedly by operating handle 122 withoutresetting the keys, because until dogs 15 are actuated by pins 17 on thereturn strokes of the levers 10, as above described, the bars 1 willremain iu their locked positions. -Thus any number may be set on thekeyboard and repeated any number of times without resetting thenumeralkeys by holding key 127 down.

IIO

This key may be provided with suitable detents to hold it in raised orlowered position at will of the operator.

The error -keJf-If the operator should make an error in setting the keysby depressing the wrong key, he can release the keys and reset themwithout having to operate the handle 122 by means of an errorkey 75,which is arranged at one side of the machine and is connected toan arm71 on the rock-shaft 6, upon which the catch-levers 5 are pivoted.Attached to said shaft 6 is a bail 74:, which extends up beside and inrear of the upper arms of catch-levers and when key 75 is depressed bail71 engages these arms and rocks levers 5, so as to force bars 1forwardly, and thus release any depressed keys, which can thereafter bereset. The arm 71 is normally upheld by a suitable spring, such as shownat 71, Fig. 2.

The recording or printing mechanism The printing mechanism comprises aseries of type-bars S8, each carried on the rearwardly-extending lowerend 89 of a lever 10 and guided in slots in a guide-bar 90, so that thesaid type-bars will be moved coincidently with the movement of thelevers 10 to present for impression the type corresponding with thesymbol of the key depressed. As many printing-hammers 91 are used asthere are type-bars in the machine, and these hammers are mounted in aframe 92, which is pivoted upon a shaft or spindle 93, so as to becapable of being tilted away from the type-bars in adjusting paper, dsc.As

vshown in detail in Fig. 4, there is an actuating-lever 95 and spring 96for each hammer 91, which normally tends to project the hammerforwardly. Each hammer is suitably mounted and guided upon `bars orantifriction-rollers 91a 91D or otherwise, (see Fig. 4,) and each has anelongated notch-engaging lever 95, so as to permit the rebound of thehammer to withdraw it from and prevent smirching of the paper. Thehammers are cocked by means of a plate 97, siidably mounted upon the topbar of a U -shaped frame 9S on the shaft 93.` This plate 97 is movedlongitudinally across the path of movement of the hammers by a swinginglever 99, having a slot 100, which engages a pin 101 on the plate 97,(see Fig. 3,) and the swinging lever is provided with a pin 102, whichis engaged by an arm 103 on a vertical shaft 104, normally impelled by aspring 105 (see Fig. 1) to withdraw the sliding plate 97 from before thehammers. On shaft 101C is an arm 10o', provided with a pin 107, engaginga notch in :in arm 10S, pivoted to a rockersl1aft109 (see Fig. 3) at theopposite side of the machine. The said arm 10S projects across the pathof movement of the upper ends of rock-levers 5, and hence when saidrock-levers 5 are moved by the depression of a key the arm 10s` will bepushed inwardly by said catchdever 5, (differentialdistancesinproportion tothe distance of 5 from pivot 109,) and consequently theshifting arm 106 will be moved, and it will in turn rock shaft 104, andthe motion of the latter will be transmitted through arm 103 to thesliding plate 107 and said plate moved in front of the hammer or hammersto be cocked. 'Ihe shaft 19 is then given a quarter-turn forwardly,which permits the lever or levers 10 to shift the printing bar or barsinto position to be acted upon by the hammers, and by a further movementof shaft 19 in the same direction the wiper-cams 18 are turned overuntil a pin 110, projecting from the outermost one of said cams, cornesinto contact with a tripping-dog 111 on a lever 112, (see Fig. 1,)pivoted on the shaft 11 and having a slot in its lower end engaging apin 113 on a push-bar 114, mounted in bearings 115, said bar 114 beingadapted to engage the frame 98, carrying the sliding plate 97, and movesaid frame and plate rearwardly, cansing the plate 97 to cock thehammers 91 opposite the appropriate type-bar set by the depression ofthe key or keys, and when this has been done the pushbar 111 and hammersare retained in such position by a pressed catch-lever 116, as shown inFigs. 1 and 2. The push-bar 111 is provided with a spring 117 fornormally retracting it. The eXtreme forward movement ofthe slide 114 isaccomplished when the shaft 19 has made about a half-revolution forward,(the com plete movement of the shaft 19 in either direction being aboutthree-quarters of a revolution.) When the movement of the shaft isreversed, a pin 11S on the longer end of the arm 63 strikes aspring-trip 119 ou the catch-lever 116 and disengages said catch fromslide 114, which is immediately retracted by its spring, thus releasingthe plate 97, and the hammers are forcibly propelled into contact withthe typecarriers by their springs 96 and the printing effected.

The trip 119 (see Figs. 9 and 20) is pivotcd to lever 116, so that itcan yield as arm 63 moves in one direction, but when the arm returnstrip 119 locks to the lever and the arm in forcing the trip out of itspath vibrates the lever as described.

The paper mechanism (indicated by the drums Sat and 85 and web 8(5) maybe of the usual character, as also maybe the inkingribbon 87 and itsfeed and controlling mechanism, which are not claimed herein.

The 'total-key connections-If at any time it is desired to ascertain thetotal registered on the machine the key '75 is used as follows: Vthenkey 75 is depressed as a total-key, arm 74 is used for the purpose ofrocking the rocklevers 5 downwardly in order to carry their hook ends 14below the pins 17 on levers 10, so that said levers are free to fallforward in making the total, which operation will presently bedescribed. 'lhe lever 71 is also connected with the upper bent end of aslide 76, which is attached to the face of lever 30, (see Figs. 2 and14,) and this slide in turn has a notch 77, which engages the tailpieceof a IOO IIO

latch 34 on the lever 30, and when the slide is depressed will releasesaid latch from engagement with the pins 32 or 32a, (see Figs. 16 and17,) and the slide 76 has in addition titted to it a spring cloggingdevice 78, which when the key 75 is depressed is thrown into the path ofmovement of the pin 55 on the disk 33 in order to effect a rearwardmovement of the guide-plate 24 for the segments 22, so as to move suchsegments out of engagement with the gears of the indicatordrums, saidpin 55 engaging device 78 and forcing lever 30 forward as handle 122 ismoved backward.

The spring 71a, Fig. 2, normally elevates the lever 71, and consequentlythe slide 76, and hence when said lever 71 isdepressed by the key 75 theslide 76 is free to descend, or may be positively caused to descend by asuitable spring 76C, Fig. 25, or other device. As said slide 76 descendsits notch 77 engages the tail of the latch 34 and tilts it out of' thepath of movement of the pins 32 and 32u on disk 33, (see Fig. 25,) butthrows the device 7S into the path of movement of the pin 55, and hencethe lever-30 is acted upon by said pin 55 through latch 78 to vibratethe lever 30, and consequently vibrate the plate 24.

A guide-plate 79, slot-ted to receive and guide the main vibratinglevers 10, may be employed. (See Fig. 1.)

In order to reset the registering-disks, it is desirable to disengagethe pawls 50 therefrom, and for this purpose l provide a bail 51,overlying the pawls 50 and attached to a rock-shaft 51, having an arm52, which is curved upwardly and inwardly in position to be engaged byone end of a pivoted lever 53, pivoted on the .side of the casing, (seeFigs. 1 and 30,) the other end of which is provided with a pivotedspring-held trip 54, which is provided with an arm 73, connected bya rod72 to the arm 71, so that when key 75 is depressed the trip 54 is throwninto position to engage a notch 33a in disk 33, and as the handle 122 ismoved forward, so as to oscillate lever 53, causing it to rock shaft 51and cause bail 5l to disengage the pawls 50 from the register-wheelgears.

The indicator mec7iam'sm.-An indicator mechanism comprising as manyindicatordrums 80 as there are registering-disks is mounted in carriage47. The object of this indicator mechanism is to show the number ofmovements of the shaft 19--that is to say, complete strokes of thehandle 122 when the register-wheels are laterally shifted, ashereinafter explained. Each drum is provided with a gear 81, (see Figs.1 and 5,) dogged by a spring-dog 82, (see Fig. 1,) and each drum as themovement ofthe carriage brings it into position is actuated step by stepor tooth by tooth by means of a spring-retracted pusher 83, mounted insuitable bearings in the machine-framing and actuated by a pin 62 on arm63 at each movement of shaft 19.

If desired, a friction-spring 65 (see Figs.

1 and 2) or other suitable detent may be used to act against a pin 65ilor the end of the lever 30 in order to hold the said lever againstaccidental displacement in the vibration of the rack-bar carrier. Also,if desired, a series of lingers 66 may be used to cooperate with thelevers 39 and the gears of the registering-wheels to insure theproperalinement of the printing-bars in printing totals. These fingersmay be mounted upon arms 67, pivoted to a shaft 63, having an arm 69,connected by a rod 70 with lever 71, as shown in`Fig. 2.

The mechanism will be suitably inclosed, and, as shown at 120, a casingmaybe placed over the 'registering -wheels having sightopeningscoveredby a perforated slide 121, (see Figs. 1 and 15,) the perforations insaid slide being of a size to expose only one numer'al on each wheel ata time, so that 'by movement of the slide to the right or left only thedesired line of numerals will be eX- posed,while the adjacent line willbe covered.

The indicator-drums 8O also may be similarly covered.

The shaft 19 has applied to'itexternally of the machine a crank, handle,or other operating device 122. (Shown in dotted lines in Figs. 1 and 2.)The handle and shaft 19 move through an arc of about two hundred andseventy degrees, this movement being limited in the forward direction(to set the mechanism) by a stop-pin 123 and in the reverse direction(to effect the registering and printing) by a stop-pin 124.

It is desirable in order to avoid interference with other parts of themachine that the registering-wheel carriage 47 be locked againstmovement excepting when the handle 122 is in the position indicated inFig. 2, and hence I interpose a latch 130, (see Fig. 1,) engaging alinednotches in the carriage and its platform and pivoted at 131 and actuatedbya pin 132 ou arm 26 engaging a slot 133 in the latch 130. This lockingdevice is intended to prevent sliding of carriage except when handle 122is in forward position, at which time the segments 22 are tilted backaway from the disks 14, thus allowing said disks to pass freely in frontof segments when latch 48 is depressed.

Operations.

Having thus described the various mechanical features and constructionsof parts and incidentally their operations, I will briefly eX- plain themanner of using the machine in various arithmetical calculations forwhich it is adapted.

lllultz'plt'cdton.-In order to multiply, it is necessary to depress keyscorresponding to the figure to be multiplied. For example, if the sumwere four hundred and thirty-two to be multiplied by twenty-four the 4key in the hundreds-column would be depressed,and then the 3 key in thetens-column and the 2 key in the units-column, and then the re- IOO IIO

peating-key is depressed. By the depression of the repeating-key 127 thedepressed numeralkeys will be retained in their depressed coudition andrestrained from release. The handle is then given four fullstrokes,which will reciprocate the levers 10 fou r ti mes and result inaccumulating on the registering-wheels four hundred and thirty-two fourtimes, or, in other words, multiplying that sum by four. The handle 122is then given a full t'orward movement and left there as in Fig'. 2.This operation will result in partially unlocking the registeringwheelcarriage 47 and also throw out of gear the segments 22, so that thecarriage can be moved in t'ront of the latter by manipulation of thelever-1S and a lateral movement of the carriage, and in this movementthe segment corresponding to the units will be in position to engage thegear of the tens register-wheel. The handle is then returned to normallower position, completing` its full stroke, and is then given asecondfull stroke, and the result indicated on the registering-wheels willcorrespond to multiplying by twenty, and since the multiplication byfour units has been. previously eifected and noted the two operationswill result in accumulating on the registering-wheels the product of thesnm. At the same time the reading on the drums S0 will be twenty-four,indicating that the handle has been properly operated, since said drumsare actuated as described by actuation of shaft 1t). In multiplyiug` anddividing the paper should be swung back away from the type, so that noprinting is done duringmultiplying or dividing operations; but thetotals may be printed after such operations are completed. It it bedesired to print the answer, the keys that. are down are first released,and then the handle is given its forward stroke Iand left there, and theindicator-carriage is brought into normal position. 'lhe handle is thenreturned to its normal position, and the total-key is depressed and acomplete stroke of the handle made. The product will then be printed onthe slip, and the machine cleared and ready t'or anothertransaction,zeroappearing on all the registering-disks at all of the sight-openings.

Division-To divide, the machine is first brought to zero, and then thesum to be divided is put on the registering-wheels as follows: If, forexample, six hundred and thirtytwo is to be divided by twenty-four, the3 key in the third column is depressed and the t5 key in the secondcolumn and thel 7 key in the first column, using that key whose numberadded to the number to be put on the drum will make nine. rPlien all of-the nine keys remaining to the left of the depressed keys are presseddown, and one. complete stroke of the handle 122 is made, and thisoperation will put the sum on the registering-wheels and also move thecarryingpins 44 into proper position for all minus 0perations. Thesight-opening slide is then shifted to the right, which will expose toview the other set of figures on the registeringwheels, and 632 willshow in the sightopenings. 'lhen 24 is set on the keyboard, as inadding, and the repeating-key 127 is depressed, so as to prevent therelease of the keys expressing twenty-four until the operation iscompleted. rlhen the handle 122 is turned forward, as in Fig. 2, andleft there, and the registering-wheel carriage is 'shifted to the right,thus taking out of action the units registeriug-wheel, and hence (33 onthe registering-wheel will come under the 24 on the keyboard, and inthis way the segments 22, corresponding to the depressed numeral-keys 2and 4, will be in position to engage the gears on the registering-wheelsindicating the number 63. The handle 122 is then returned to normalposition, thereby completing one reciprocation, and 392 will appear inthe sight-openings. Since the 39 ot' 392 is greater than the 24, thehandle 122 is given one more full reciprocation, resulting in 152appearing in the sight-openings, and since the 15 of 152 is less thantwenty-four the registering-wheel carriage is moved one notch to theleft, and this is permitted by moving the handle 122 forward ahalt-stroke and releasing the lever 4S. rl`hese movement-s will resultin bringing the registering-wheel containing 52 under the 24 keys inposition to have their gears engaged by the segments 22. The handle 122is now returned to normal position, and 12S will show in thesight-openings. Since one hundred and twenty-eight is greater thantwenty-fou r, the operation oi the handle 122 is continued as long asthe amount in the sight-openings is greater than twenty-four, and in theexample in question tive more i'ull strokes ot' the handle Will berequired, and then 8 will show in the sight-openings, same being theremainder. The upper drums will show the quotient and the depressed keyswill show the divisor.

Sttbtrdction-1`o subtract, first put the tninuend on the drums bydepressing the numeral-keys, as for dividing. For example, to subtracttwenty-four from six hundred and thirty-two the 3 key in the thirdvcolumn, the G key in the second column,

and the 7 key in the first column of keys are depressed, and also all ofthe nine keys in the columns to the left of the depressed keys. To getcarrying-pins 44 in position for minus operation, the handle 122 isgiven one full reciprocation, and this will put G32 on theregistering-wheels. The sight-opening slide is also moved to the rightto bring the minus set ot' figures into view. The number to besubtracted is then put on the keyboard same as for adding, and thehandle is reciprocated once, and the answer will appeal' at thesightopenings.

The reason for depressing 2 in order to have 7 show in the sight-openingin all minus operations is because the drums always move in the samedirection, and the drnm in the plus-column reads from O to El while inthe minus-column the figuresA 9 H on the drum read from il to 0, andconsequently if 7 is to appear in the minus sight-opening the 2 key(whose 2 on the plus-column is opposite the 7 on the minus-column ot'figures on the registering-wheel) must be pressed, and this results inadvancing the dru ms two teeth when the handle is operated, and sincethe 7 on the minus-column travels with it it will appear in the minussight-opening. The reason the zeros are not opposite each other is foundin the fact that the pin 44, which effects or causes the carrying to bedone when the amount on the drum becomes greater than nine, acts onlywhen the roller advances to the tenth tooth in all plus operations,whereas in all minus operations the pin must act promptly at thebeginning of the movement of the drum, and consequently it must beadvanced nine teeth, which will bring it into position to act as soon asthe drums are advanced one or more teeth.

To print the total, the segments are left in gear during the forwardmovement of levers 10, thus rotating the registering-wheels backwardlyuntil pins 445 in gears 43 st-op against tripping-finger 45, when theregistering-wheels will stand at O and the proper type will be presentedfor printing.

When using the machine for purposes of addition, a key isdepressed ineach row to correspond with the figures of the item, and then the handleis moved one full stroke, resulting in the restoration of all of thedepressed keys to their normal position and the printing of thecorresponding figures on the slip and the accumulation thereof on theindicator-drums'. This operation is repeated until every item is added.When the total is to be printed, the total-key is first depressed andheld down during the complete stroke of the handle. This operation willalso clear the machine and restore the indicator-drum to Zero. Il it bedesired to leave the total in the machine to be carried into anothertransaction, the same operation is repeated, excepting that thetotal-key is released at the end of the forward movement of the handleand before the handle is returned to normal position.

Of course the machine by obvious changes lnay be adapted for calculatingmoney transactions in systems other than dollars and cents.
